I had the same set up but with trinity stage iv ss in frame pipes,stage 11 porting 19cc domes 35pwk 58,pilot DEK needle, 5th clip 210 main, This fucken motor ripped. It would pull hard out the hole & pull hard in 6th gear 15/40 when you hit sixth gear the motor will still be pulling, no flat spots. None.Them pipes & porting was a great combo.
